I have not had any experience with 3d projectors but have had a good 3d experience with Full HD projector at one of our forum member's, Srinisundar, place. We watched "Journey to the Center of the Earth", had an awesome, tongue-in-cheek experience.
I was thinking of going for a HD66 but later changed my mind and went for a HD20. As i won't be watching much of 3d stuff and secondly i think the technology is still evolving.
av Max reviewed few projectors & Sharp PG-D2500 Projector is 3Dready.It has scored well(4/5)only a con is greyshades in dark scenes.Otherwise its is better & cheaper(60k)
